CAT5133集成電路（IC）的數字電位計規(guī)格書PDF中文資料

DESCRIPTION

The CAT5133 is a high voltage Digital Programmable Potentiometer (DPP) integrated with E2PROM memory and control logic to operate in a similar manner to a mechanical potentiometer. The DPP consists of a series of resistive elements connected between two externally accessible end points. The tap points between each resistive element are connected to the wiper outputs with CMOS switches.
